Groundwater Sustainability Plans

The Sustainable Groundwater Management Act (SGMA) requires local Groundwater Sustainability Agencies (GSAs) in high- and medium-priority basins to develop and implement Groundwater Sustainability Plans (GSPs) or to develop Alternatives to GSPs. GSPs provide a roadmap for how groundwater basins will reach long-term sustainability.

GSPs are submitted to the Department of Water Resources’ (DWR) SGMA Portal. GSPs for critically overdrafted high- and medium-priority basins were initially due to DWR by January 31, 2020. GSPs for the remaining high- and medium-priority basins were due to DWR by January 31, 2022.

Although local public agencies in basins designated as low and very-low priority are not required to do so, DWR encourages them to form GSAs and develop GSPs, update existing groundwater management plans, or coordinate with others to develop a new groundwater management plan in accordance with Water Code Section 10750 et seq.

GSP Evaluation

The Department of Water Resources (DWR) evaluates GSPs to determine if they comply with SGMA, substantially comply with the GSP Regulations, and whether implementation of the GSP is likely to achieve the sustainability goal for the basin. DWR’s evaluation and assessment is based on criteria outlined in the GSP Regulations.

DWR evaluates GSPs within two years of their submittal and issues a written assessment. See the GSP Evaluation fact sheet for more information on GSP assessment outcomes.

GSP Assessment Materials

For more information related to the GSP Assessments released in January 2022, please find the following materials:

DWR released GSP Assessments prior to its statutory deadline and press releases on those evaluations can be found from June 2021 and November 2021. DWR hosted a live question and answer webinar on June 24, 2021. Below are the materials from the webinar:

 

Please view this short video message from the Department of Water Resources (DWR) on the first GSP Evaluations.

Annual Reports

SGMA requires GSAs to submit annual reports to DWR each April 1 following adoption of a GSP. Annual reports will provide information on groundwater conditions and implementation of the GSP for the prior water year. DWR has prepared information and answers to frequently asked questions on the GSP annual reports in the following document:

GSP annual reports will be submitted to DWR's SGMA Portal. Resources for GSAs submitting annual reports are available on the Resources Page on the SGMA Portal.

If you have any other questions about GSP annual reports, you can email GSPSubmittal@water.ca.gov.

GSP Initial Notification

GSAs are required to provide a GSP initial notification prior to initiating development of a GSP. The initial notification provides to the public, and the Department, a written description of the manner in which interested parties may participate in the development and implementation of the GSP. The GSA shall make the information publicly available by posting relevant information on the GSA’s website.

GSAs are required to provide the GSP initial notification written statement to the legislative body of any city, county, or city and county, located within the geographic area to be covered by the GSP to coordinate land use and water management planning. In addition, if the geographic area to be covered by the GSP includes a public water system regulated by the Public Utilities Commission, the GSA shall provide the written statement to the commission.

Related to the GSP initial notification is a “maintenance of interested persons list”. A GSA is required to establish a list of persons interested in receiving notices – any person may request, in writing, to be placed on the list of interested persons. Also, GSAs are required to encourage the active involvement of diverse social, cultural, and economic elements of the population within the groundwater basin prior to and during the development and implementation of the GSP.

GSAs are required to submit GSP initial notification information to DWR using the SGMA Portal – GSP Initial Notification System. For more information see Water Code §§ 10723.4 and 10727.8 and 23 CCR § 353.6.

The purpose of this frequently asked questions document is to inform groundwater sustainability agencies (GSAs) about the groundwater sustainability plan (GSP) initial notification requirements, as described in the Sustainable Groundwater Management Act (SGMA) and the GSP Regulations. Additional details are also provided in this document regarding coordination agreements and the identification of a plan manager, as well as a basin-wide point of contact if multiple GSPs are expected.

GSP Submittals

GSPs submitted to DWR are available online on DWR’s SGMA Portal. DWR will post GSPs within 20 days of submittal for public viewing. DWR’s posting starts a public comment period. Public comments are welcomed and encouraged - a SGMA Portal account is not necessary.

More information about how to comment on a GSP can be found in the following set of frequently asked questions:

For GSAs that are currently preparing GSPs, DWR hosted two workshops and a webcast to provide an overview of the online GSP Reporting System in 2019. The webcast is available below under Resources and Guidance.

Additional materials detailing the step-by-step process for submitting a GSP online through the GSP Reporting System can also be found below.

Regulations

Under Water Code Section 10733.2, DWR was required to draft and adopt emergency regulations for the evaluation of GSPs and Alternatives, the implementation of GSPs and Alternatives, and coordination agreements. 

The GSP regulations were developed following a comprehensive, multi-phased public outreach and engagement process. Throughout 2015 and into 2016, DWR met regularly with numerous SGMA advisory groups and conducted public meetings and webinars to gather perspectives from other statewide stakeholders, partners, and local agencies. The input received was considered in the Draft GSP Emergency Regulations.

On May 18, 2016, the proposed GSP Emergency Regulations were presented to the California Water Commission for consideration of approval. The California Water Commission unanimously approved the proposed regulations, as written, and we submitted the Final GSP Emergency Regulations and the Notice of Proposed Emergency Rulemaking to the Office of Administrative Law
